Kessler discussed the revelations with talk-show host and gay author Michaelangelo Signorile Friday on his Sirius Radio show.

According to the book, Rice owns a home together with Randy Bean, a documentary filmmaker who once worked with Bill Moyers. Kessler made the discovery by looking through real estate records.

Bean explained the joint ownership and line of credit to Kessler by saying she had medical bills which left her financially drained and Rice helped her by co-purchasing the house along with a third person, Coit Blacker, a Stanford professor who is openly gay.

Blacker later sold his line of credit to Rice and Bean.

Kessler mentions rumors about Rice's sexuality in the book and notes that many older single heterosexual women have been "unfairly" targeted with regard to their sexual orientation. He also says Rice has been the focus of "nasty attacks."

When asked about the revelations on Signorile's show, Kessler "said he did not know if this meant there was something more to the relationship between the woman beyond a friendship."

Perhaps the most popular remaining high-profile figure in the Bush Administration, Rice was promoted to succeed Bush by many of her backers. She repeatedly declined offers to run for president in 2008 and will return to Stanford upon her departure from the White House.

Rice faced attacks from liberals in the gay community over the State Department's reluctance to rebuke Iran for the hanging of gay teenagers. The gay rights lobby Human Rights Campaign called on Rice in 2005 to condemn Iran's human rights abuses after the hanging of two gay teenagers, and to express indignation over "other horrific human rights abuses against gay, lesbian, bisexual and transgender people across the globe."

Rice did not.

The Secretary has remained silent on whether gays should be allowed to serve in the military and has not commented on the permanent partners immigration act.

Andy Humm, a New York gay journalist who discussed the Iran hangings on his TV show Gay USA, says Rice's silence gives "consent."

"Condi Rice works for an administration that uses attacks on gay rights to win votes," Humm told RAW STORY. "She has stood by silently while the President has proposed writing anti-gay discrimination into the Constitution of the United States. Whenever she is given the opportunity to distance herself from their anti-gay polices she punts."

"After she became secretary of state, she came to a party at Blacker's house, kicked off her shoes, and began dancing through the night to rock and and roll," Kessler wrote. "Blacker, who is gay, wanted to show his partner how tight her behind is; he postulated that if he aimed a quarter at her butt, it would bounce off like a rocket. He was right. Rice, who was dancing, didn't realize what he had done until everyone began laughing hysterically. She was flattered -- and proud."

The blogger who first posted emails about former Rep. Mark Foley's (R-FL) solicitation of male Congressional pages, Lane Hudson, also questions Rice's silence.

"Secretary Rice has typified the juxtaposition that many Republicans have between their public and private lives," Hudson said. "Privately, she is very supportive of gays. However, she heads a State Department that has done little to move foreign governments around the world in the direction of equal rights for their citizens."

Steve Clemons, who blogs at The Washington Note -- and who travels in high-level foreign policy circles -- told RAW STORY that "Condoleeza Rice may or may not be gay but she is in a relationship which legitimately raises these kinds of questions. Before he took office, the president and first lady had close relationships with a number of gay men, including Charles Francis, whose brother managed Bush's reelection campaign for Texas governor."
